Stefan Bischof commented on FELIX-5844:
---------------------------------------
Hi,
you're right, setting the objectClass to null isn't the right way.
What i tried to do is to get the same result as
ServiceRegistry.getServiceReferences(null, "(osgi.jaxrs.resource=true)")
by using a @Reference annotated method.
I want to get these JAY-RS recource services
{code:java}
As JAX-RS resources have no common interface type they are instead registered
with the osgi.jaxrs.resource service property with a value of "true". This
property serves as a marker to the JAX-RS whiteboard runtime, indicating that
this OSGi service should be hosted as a JAX-RS Whiteboard resource.
(OSGi Spec 151)¶ {code}
any idea?
